This invention relates to a seat regulator especially adapted for folding seats.

It is the object of this invention to present a seat regulator thatis simple in construction, easy to operate and that can be assembled and dissembled with a minimum l.of

effort. To this end we provide a seat support, a frame pivoted to that support and adapted to removably and slidably engage a plurality of slotted plates which are fixed to the seat frame.

In the drawing: Fig. 1 is a vertical section on the line 1--1 of Fig. 2.

Fig. 2 is a bottom plan view of the seat on the line 2-2 of Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 2. Referring more particularly to the drawing, we have shown a slidable seat which con- 20 sists of aY seat bottom which may be referenced l, to which is attached the seat back 2. Attached to the underside of the seat bottom is a plurality of slotted guides which aredesi ated 3. Each guide has a longitudinal s ot 4 which is enlarged at one end as at 5. A triangular frame 6 having depending lugs 11 and 12 at its forward vertices is adapted to slidably engage the slotted guide plates lby means of the headed studs 7 which are fixed to the vertices and which are adapted to slide within the slots 4.

The seat is supported from a fixed part of the automobile, which is here shown as the ioor 8, by means of the rear legs 9 and the front supports 10. Since the seat bottom and the rear legisware adapted to move forwardly and bac ardly, and the front supports are stationary, it is obvious that the anar dispositions of the seat bottom relative to the oor will chan e in degree. Therefore, that the seat may e adjustable, the seat bottoml must be pivotally connected to the iioor supports. Hence, to achieve such atrue and workable combination, the triangular frame is adapted to pivotally .engage the front seat supports 10 by means of the lugs 11 and 12 which pivot about the pins 13 which are secured in the seat supports 10.

The seat is adapted to be adjusted by a seat 50 regulator comprising a screw 14 which is adapted to be turned by any suitable crank 2l, p and which is journaled in the bearing member 15. The collars 16 and 17 allow the screw to rotate in the bearing member 15 but prevent longitudinal movement Of the said screw. The screw operatively engages the travel nut 18 which is fixed to the triangular' frame member.

The seat is so constructed that its rearward movement will be stopped before the studs reach the enlarged ends 5 of the longitudinal slots '4 in the guide plates 3, and in this case the bearing member 15 is adapted to abut against the triangular frame the instant the headed studs 7 reach the enlarged ends 5 of the longitudinal slots 4. Hence, there is no danger of4 the seat being dissembled during its operation.

In order to assemble the seat the guide plates 3 are attached tothe seat frame. The studs on the triangular frame arethen in- ,serted into the enlarged ends of the slots in theguide members and from thence moved longitudinally so as to engage the narrow portion of the slot. Then the screw is turned into the travel nut and the screw and its bearing 15 subsequently fixed to the seatframe.

From the foregoing description it is obvious that we have presented a seat regulator that is characterized by its simplicity of structure and ease of assembly.

What we claim is:

1. An adjustable seat having in combination a seat bottom, a support therefor, a slotted plate and stud guide members between the seat bottom and the support, and a screw and nut adjusting device for adjusting the seat bottom along the support, the said slotted plates having openings at one end of the slots, and the screw and nut being arranged so that the openings cannot be reached by the studs within the range ofV adjustment of the screw and nut, but the seat bottom may be disassembled from the support by disengaging the screw.

2. An adjustable seat comprising a seat bottom, a plurality of slotted plates secured to the seat bottom, 'a support for the seat comprising a frame member having a. pluralido ity of headed'studs adapted to slidably engage the slotted plates in the said slots and lnteroonnect the support and the seat, manually o erable adjusting means secured to the 5 said rame and said seat bottom, the Said slotted plates having the slots enlarged at their forward ends, the said adjusting means being arranged so that the enlarged ends of the slots can not be reached by the studs 10 within the range of adjustment of the adj ustin means, but the seat bottom may be f disassem led from the support by disconnecting the adjusting means from the seat bottom. 15 In testimony whereof We have axed our s1gnatures.
